On-Board Connector Overview 18

The on-board connectors 18 are arranged along the side edge of the circuit board 17 to correspond to the respective socket holes 17H and are fitted with the respective relay connectors 14 through socket holes 17H. Each on-board connector 18 includes a housing 60 made of insulating material such as a synthetic resin and further includes a metal output terminal 70 completely contained in housing 60.

Housing 60 is a one-piece component including a terminal holding portion 61 and an insulating portion a (i.e. a reinforcing portion) 62. Terminal holding portion 61 forms a block-like shape, wherein a locking recess .63 is formed to have a vertically elongated rectangular opening in the outer surface (i.e., the circuit panel facing surface 17) of the housing 60. The position and size of the locking recess 63 when the on-board connector 18 is mounted on the circuit board 17, they are arranged to substantially correspond to those of the socket 17H. Relay connector 14 may be fitted into the socket recess .63. In the socket recess 63, a pair of upper and lower positioning portions 64 are formed as rib-like protrusions so as to protrude from the inner surface closest to the edge portion 17E of the circuit board 17. The pair of positioning portions .64 are located vertically, substantially in the center of the locking recess 63. In addition, a support slot 65, wherein the output terminal 70 is mounted (or supported), is provided within the portion of the recess. terminal support 61. The support groove 65 is formed across the recess recess 63 and has an elongated opening extending on the surface facing housing circuit panel 17 and along the direction. perpendicular to the edge portion 17E of the circuit board 17. Support groove 65 includes a first portion of groove 65a formed from a deep recess in the superstructure. inner edge of the recess recess 63, away from the edge portion 17E of the circuit board 17, a pair of second portions of the slots 65 formed of recesses extending to the respective upper and lower sides of the recess. far end portion (i.e., the farthest end portion of the edge portion 17E) of the first slot portion 65a and a third slot portion 65c formed from a recess extending between the pair of positioning portions 64 of the surface socket recess 63 closest to the edge portion 17E of the circuit board 17.

The terminal holding portion 61 is formed to be larger than the insulating portion 62 described below in thickness measured from the rear surface of the circuit board 17, such that a shape substantially similar to a step is formed between them. A tapered surface 61 s is formed on the outer surface of the terminal holding portion 61 on the opposite side of the circuit panel 17 by cutting the edge of its corner from the insulation portion side 62 at an angle of 45 °.

Insulation portion 62, that is, a portion that does not include the

70 is disposed closer to the edge portion 17E of the circuit board 17 than the terminal holding portion 61 so as to be continuous with the lateral surface of the edge portion 17E of the mounting portion. 61. The surface facing the circuit panel 17 of the insulation portion 62 is continuous and flush with the surface facing the circuit panel 17 of the terminal holding portion 61. The insulation portion 62 is the same as the terminal holding portion 61 in width (i.e., length along the vertical direction parallel to the edge portion 17E of the circuit board 17). The upper and lower outer surfaces of the insulating portion 62 are continuous and flush with their respective surfaces are only upper and lower outer surfaces of the terminal holding portion 61. The horizontal length (i.e. the length along a direction perpendicular to the edge portion 17E of the circuit board 17) of the insulation portion 62 is substantially half of the horizontal length of the terminal support portion 61. The insulation portion 62 includes a pair of thin-walled portions upper and lower 62a having a block-like shape and further including a thick wall portion 62b disposed between the thin-walled portions 62a and having a block-like shape. The insulating portion 62, when viewed from the edge portion 17E side of the circuit board 17, forms a laterally facing T-shape. The metal reinforcing pins 66, perpendicularly elongated with respect to the rear surface of the circuit board 17, are embedded in the respective thin-walled portions 62a. An extreme portion of each reinforcing pin 66 protrudes from the surface facing the circuit board 17 of the thin wall portion 62a outwardly and is seated in the positioning hole 17a. The locking structure between the reinforcement pin 66 and the positioning hole 17a serves as a means of a reinforcement for securing the housing 60 to the circuit panel 17. The reinforcement pins 66 of the reinforcement means may be formed of terminals. or, alternatively, may be formed of synthetic resin terminals. Strong welding, adhesive bonding or welding can be used as a reinforcement method associated with the locking structure. A positioning recess 62c is formed in the thick wall portion 62b so as to have a circular opening on its outer surface on the opposite side of the circuit panel 17. The positioning recess 62c serves as a positioning means when a cover , not shown, or similar is mounted on the power panel 16 on the rear side. Its geometry axis is perpendicular to the rear surface of the circuit board 17. Output Terminal 70

The output terminal 70, which may be formed by bending a metal material that is formed into a predetermined shape by means of a perforation, includes a proximal portion 71, a supported portion 74, a flexible portion 72 and a connecting portion 73. The output terminal 70 is mounted in the holding groove 65 on the face side of the circuit panel 17 of the terminal holding portion 61.

The proximal portion 71 has a rectangular shape similar to the elongate plate in a direction perpendicular to the rear surface of the circuit board 17, so that its surface is arranged substantially parallel to the edge portion 17E of the circuit board 17. The connector 71a having a small width is provided at the proximal end of the proximal portion 71 (such that the connector pin 71a of the output terminal 70 and the reinforcement pins 66 of the isolation portion 62 are collectively provided at least three positions each). The proximal portion 71 is held in the second groove portion 65 by snap-fit, while small projecting portions formed on the side edge portions of the proximal portion 71 are embedded in the inner walls of the second groove portions 65b. As a result, output terminal 70 is maintained to be substantially and completely contained in terminal holding portion 61, except for connector pin 71a. Connection pin 71a penetrates through a connection hole 17b of circuit board 17 and which is connected to the circuit. Housing 60 is fixed to circuit board 17 due to connector pin 71a engaged in connector hole 17b.

The supported portion 74 generally forms an elongate shape having a width less than that of the proximal portion 71 and is disposed in the deep portion of the first slot portion 65a, i.e. disposed away from its opening. The supported portion 74 extends substantially and orthogonally from the extreme portion of the proximal portion 71 on the opposite side of the connector pin 71a toward the edge portion 17E of the circuit board 17. That is, the supported portion 74 is elongated in a direction substantially parallel to the rear surface of the circuit board 17 and substantially perpendicular to the edge portion 17E of the circuit board .17. The supported portion 74 is smaller than the near portion 71 in length.

The flexible portion 72 generally forms an elongate shape about the same width as the supported portion 74 and extends substantially and orthogonally (or substantially parallel to the proximal portion 71) of the distal end (i.e. the extreme portion on the opposite side of the proximal portion .71) of the supported portion 74. The flexible portion 72 is slightly smaller than the proximal portion 71 in length. The flexible portion 72 is retained in the first slot portion 65a so as to be able to be inclined at an acute or obtuse angle to the supported portion 74 due to its elastic deformation.

The connecting portion 73 generally forms an elongate shape having the same width as the flexible portion 72 and specifically form a substantially U-shape having a narrow open end. The connecting portion 73 includes a first strip portion 73a that forms a loop at the distal end of flexible portion 72 and extends in a direction away from the circuit panel 17 and further includes a second strip portion 73b that forms a loop at the distal end of the first strip portion 73a and extends in one direction towards the circuit board 17. At the connecting portion 73, the distance between the strip portions 73a, 73b is partly set to be shorter. The shortest distance portions of the strip portions 73a, 73b are located in the recess recess 63. The first strip portion 73a is disposed along the inner surface of the recess recess 63 of the edge portion 17E. of the circuit panel 17 so as to be partially contained in the first slot portion 65a. The second strip portion 73b is disposed along the inner surface of the socket notch 63 further from the edge portion 17E of the circuit board 17 so as to be partially contained in the third slot portion 65c (or partially disposed between the pair). of positioning portions 64). The power panel 16 thus constructed is mounted on chassis .13 by being moved toward chassis 13 from the rear, while circuit board 17 is kept parallel to chassis 13. The mounting direction of the connectors on-board 18 to relay connectors 14 is directly opposite to the discharge pipe mounting direction 15 to relay connectors 14. That is, the snap-in direction of on-board connectors 18 is parallel to the direction pipe assembly 15 to the relay connectors 14. At the time of attachment, the wall portion 27 of each relay connector 14 and the panel connection portion 33 disposed along the wall portion 27 penetrate the control panel. 17 through the slot hole .17H and are inserted into the socket recess 63 of the on-board connector 18 so that they are located between the first strip portion 73a and the second strip portion 73b, as shown in the figures. 9 and 11. As a result Accordingly, the wall portion 27 has contacts with the first strip portion .73, while the panel connecting portion 33 has contact with the second strip portion 73b. Further, the connecting portion 73 deforms elastically to increase the distance between the first strip portion 73a and the second strip portion 73b. Relay connector 14 is thus fitted to on-board connector 18, and thus relay terminal 30 is con- ductively connected to output terminal 70. As a result, power panel 16 is connected to discharge pipes 15 via relay connectors 14, so that power from power panel 16 can be supplied to discharge pipes 15. When on-board connectors 18 have reached an appropriate state of being fitted into the relay connectors 14, power panel 16 is bolted to chassis 13. Operational Effects of the present Mode

(1) Plug holes 17H are formed as through holes in circuit board 17. This allows on-board connectors 18, provided for connection to relay terminals 30 in chassis 13, to be arranged in the the rear surface of the circuit board 17 on the opposite side of chassis 13. On the other hand, the electronic components 19 free from the constraint of the positional relationship to chassis 13 may be mounted on the rear surface of the circuit board 17, such as are on-board connectors 18. Thus, according to the present embodiment, power panel 16 connected to relay terminals 30 in chassis 13 can be obtained as a single-sided power panel where the rear surface on the side opposite chassis 13 is provided as the only mounting surface.

(2) Output terminal 70 is completely contained in housing 60 (except for connection pin 71a) and thus can be protected from interference with foreign or different substances.

(3) Relay terminal 30 is inserted into socket recess 63 to be connected to output terminal 70. Thus, foreign substances are prevented from interference with the connection between relay terminal 30 and terminal. output 70.

(4) the output terminal 70 is blocked by the positioning portions 64 provided on the inner surface of the input recess.

63, so that the displacement of the output terminal 70 in the vertical direction parallel to the edge portion 17E of the circuit board 17 is restricted. Therefore, the flexural stiffness of output terminal 70 need not be increased to prevent displacement. The reduced flexural stiffness of output terminal 70, thus provided, results in reduced frictional resistance developed when relay terminal 30 is connected to output terminal 70. Thus, operating efficiency when relay terminal 30 is connected to output terminal 70 can be improved.

(5) The output terminal 70 is formed to include a proximal portion 71 secured to housing 60, a flexible portion 72 extending from proximal portion 71 (through the supported portion 74) and capable of elastic deflection and a connecting portion substantially U-shaped 73, extending from flexible portion 72 and capable of resiliently tightening relay terminal 30. Panel connection portion 33 of relay terminal 30 may contact only the second strip portion 73b of the two strip portions 73a, 73b of the connecting portion 73, that is, the free end side strip portion on the opposite side of the flexible portion 72.

According to the construction, if the panel connecting portion 33 of the relay terminal 30 moves relatively towards one side of the flexible portion 72 within the socket recess 63, all of the connecting portion 73 (i.e. the first strip portion 73a and second strip portion 73b) move to the side of flexible portion 72 (or to the side of proximal portion 71) together with the panel connecting portion 33 while pushing the flexible portion 72 for elastic deflection. In this way, the connection between the panel connecting portion 33 and the second strip portion 73b can be maintained.

Conversely, if the panel connecting portion 33 moves relative to the free end or opposite side of flexible portion 72, the second strip portion 73b on the free end side is pushed by the relay terminal. 30 moving without remarkable elastic deflection of the flexible portion 72. Then, the connection between the panel connecting portion 33 and the second strip portion 73b can also be maintained. Note that the first strip portion 73a is currently detached from the wall portion 27.

(6) In the construction including a plurality of onboard connectors 18 and a plurality of relay terminals 30 arranged in lines, output terminals 70 may move towards relay terminals 30 for a reason such as difference in thermal expansion rate between non-metallic circuit board 17 as a mounting base for on-board connectors 18 and metal chassis 13 as a mounting base for relay terminals 30.

In view of this, as shown in Figure 9, the connector portion 73 is provided at the output terminal 70 so as to be elongated in a direction substantially perpendicular to the assembly direction of the on-board connectors 18 (i.e. 9), while the panel connection portion 33 is provided at relay terminal 30 to form a plate-like shape parallel to the joint direction of the on-board connectors 18 (i.e. vertical direction in figure 9) and be larger than the connecting part 73 in width (ie length along a direction parallel to the assembly direction of the on-board connectors .18). The panel connecting portion 33 is arranged to contact the connecting portion 73.

According to construction, the panel connecting portion 33 is arranged to be large in length along the joint direction of the on-board connectors 18 and thus the connection between the panel connecting portion 33 and the connection portion 73 may be retained even if relay terminal 30 moves in the overall direction of output terminal70.

(7) In view of a high voltage applied to the output terminal 70 of the on-board connector 18 disposed along the edge portion 17E of the circuit board 17, a leak may occur between the output terminal70 and an electrically conductive conductor. approximates edge portion 17E of circuit board 17.

Therefore, in the present embodiment, the outlet terminal 70 is surrounded by the synthetic resin housing 60, wherein the outlet terminal 70 is held in the terminal holding portion 61 disposed through the insulating portion 62 of the 17E of the circuit board 17. Thus, the output terminals 70 are positioned in areas of the housings 60 on the opposite side of the edge portion 17E, resulting in narrow sectional arrangement. Thus, a low voltage area is left in a portion (i.e. the insulating portion 62) of the onboard connector 18 located in proximity to the edge portion 17E of the circuit board 17 and a long distance is left. is maintained between the output terminal 70 and the edge portion 17E of the circuit board 17. Therefore, even as an electrical conductor approaches the edge portion 17E of the circuit panel 17, a leak between the output terminal 70 and the electrical conductor can be prevented.

In housing 60, the present invention 62, which is disposed closer to edge portion 17E of circuit board 17 and does not include output terminal 70, forms a substantially block shape continuously provided over substantially the entire width of housing 60 . In this way, foreign substances can be safely prevented from approaching the output terminal side 70 of the edge portion 17E of the circuit board 17.

(9) Insulation portion 62 of housing 60, which is disposed closer to edge portion 17E of circuit board 17 and does not include output terminal 70, can effectively function as a reinforcing means for securing housing 60 on circuit board 17.

(10) The output terminal 70 forms an elongate shape substantially perpendicular to the edge portion 17E of the circuit board 17 and is positioned, in the width (or vertical direction) direction, parallel to the edge portion 17E of the circuit board. 17 so as to be substantially in the center of the housing 60. Thus, foreign substances may be prevented from approaching the outlet terminal 70 on the upper or the lower side of the housing 60, resulting in the prevention of a leakage. - left by the approach.

(11) In the housing 60, the terminal holding portion 61, provided for output terminal arrangement 70, is formed to be larger than the isolation portion 62 not enclosed in the output terminal arrangement 70, in measured thickness of the housing. circuit board 17, so that a step-like shape is formed between them. Therefore, the shape and / or size of the output terminal 70 may be established with increased flexibility.

(12) The edge portion of the terminal holding portion 61 in the insulation portion 62 is cut into a tapered shape. Therefore, when a cover is attached to the on-board connectors 18, the opening edge of the cover is prevented from reaching the housing 60.

(13) The connecting part 73 of the output terminal 70, provided as a connecting means for connection to the outside (ie relay terminal 30), cannot be covered with the housing 60, for example. functional reasons. However, the connection part 73 is therefore arranged in the recess recess 63. Therefore, the connection part 73 is less leak-proof compared to the arrangement of a connection part 73 on the outer surface of the connector. accommodation 60. Mode 2

In the following, one embodiment of the present invention will be explained with reference to Figures 17 to 28. In the present embodiment 2, the construction of the lighting device 110 differs from that of the above embodiment 1. Therefore, the same constructs are designated by the same symbols and explanations for the constructions, operations and their effects are omitted. Lighting Device Overview 110

The lighting device 110 includes a lamp unit 112 and power panels 116. The lamp unit 112 includes a metal chassis 113, which generally forms a horizontally elongated rectangular plate and functions as a reflective plate. Also included are a plurality of discharge pipes 115 held in a horizontal position and arranged vertically on the front side of chassis 113 so as to parallel each other and a plurality of relay connectors 114, which are arranged vertically along the ends. side edges of chassis 113 to correspond to discharge pipes 115. Power panels 116 are disposed on the rear side of chassis 113 to provide power to discharge pipes 115 via relay connectors 114.

A plurality of mounting holes 113H, corresponding to the ends of the discharge pipes 115, are formed through the bolt 113 to extend from the front side to the rear side and are arranged vertically to be flush with 115. The relay connectors 114 are mounted through the respective mounting holes 113H.

Relay Connector 114

Each relay connector 114 includes a bracket 120 made of synthetic resin and a relay terminal 132 that is housed in bracket 120 and made of metal (e.g. stainless steel).

Bracket 120 includes a box-like portion 121 that forms a block-like shape as a whole, and further includes a wall portion 122, which protrudes behind the rear surface of the box-like portion 121. container 123 is formed in the box-like portion 121 so as to have an opening extending from the front to the side (i.e., the side on the opposite side of the side edge portion of the chassis .113). The front opening portion of the container space opening 123 is provided as a receiving opening 124, wherein an end portion (or bolt 136) of the discharge tube 115 is fitted to the front side. The side opening portion is provided as an exhaust opening 125 to prevent interference with the glass tube 134 when the extreme portion of the discharge tube 115 is held in the container space .123. A plug 126 is formed in the exhaust port 124 so as to fall into the opening edge and form a plate-like shape. Due to the plug 126, the exhaust opening 125 is narrowed to form a substantially U-shaped opening. The vertical size of the substantially U-shaped exhaust opening 125 is adjusted to be smaller than the inside diameter of the body 137. of the bolt 136 and be equal to or slightly larger than the outside diameter of the glass tube 134 of the discharge tube 115. In the exhaust port 125, a concave portion .127, having a semicircular shape, is formed at the far end portion of the edge. opening The radius of curvature of the concave portion 127 is adjusted to be equal to or slightly larger than the radius of curvature of the outer circumference of the glass tube 134. At exhaust port 125, a pair of upper and lower guide portions 128 is formed in areas of the opening edge on the front side of the concave portion 127.

In the box-like portion 121, an extended portion 129 extending parallel to the chassis 113 is formed on the side surface of the box-like portion 121 including the exhaust port 125. the extended portion 129 extends to separate the front surface of chassis 113 of exhaust port 125. A pair of upper and lower retaining protrusions 130 is formed on the outer surface (i.e. upper surface and lower surface) of the housing-like portion 121.

Relay terminal 131 is held within bracket 120. Relay terminal 131 may be formed by bending a metal plate that is formed into a predetermined shape by means of perforation. Relay terminal 131 includes a pair of vertically symmetrical elastic compression portions 132 formed of curved plates and further includes a panel connection portion 133 formed as a side-projecting flat plate-like portion. later. The pair of elastic compression portions 132, which are housed in the container space 123, may flexibly and vertically deflect to increase the distance between them. The vertical distance between the pair of elastic compression portions 132 is shorter at a position corresponding to the front side of the concave portion 127 of the plug 126. The minimum distance between the elastic compression portions 132 when the elastic compression portions 132 are not forced for elastic deflection or are in a free state, it is set to be smaller than the outside diameter of the body 137 of the bolt 136 attached to the discharge tube 115. On the other hand, the panel connecting portion 133 projects from the rear surface of the box-like portion 121 so as to be exposed to the outside of the bracket 120 and extends backwardly along the wall portion 122.

When relay connector 114 is mounted to chassis 113, wall portion 122 of bracket 120 is inserted into a mounting hole 113H on the front side of chassis 113. Thus, the outer surface of housing-like portion 121 becomes contact the opening edge of mounting hole 113H on the front surface of chassis 113, while retaining protrusions 730 are blocked and by the opening edge of mounting hole 113H on the rear surface of chassis 113. Thus, chassis 113 is interspersed between the locking surface 130 on the front side and the retaining protrusions 130 on the rear side. In this manner, the bracket 120 is fixed to the chassis 113 so that its movement in the mounting direction (i.e. the through direction of mounting hole 113H) is restricted. Then the mounting of relay connector 114 on chassis 113 is completed. When relay connector 114 is secured to chassis 113, the box-like portion 121 as the front end portion of bracket 120 projects (or is exposed) to the rear side of chassis 113. Discharge Tube 115

Each discharge tube 115 is formed of a cold cathode fluorescent tube which includes a generally elongated straight glass tube 134 having a circular cross-section, elongated metallic outer conductors (e.g. nickel or cobalt metal) 135 having a circular cross-section and projecting linearly from respective ends of glass tube 134 and coaxially with glass tube 134. Bolts 136 are still included attached to respective end portions of glass tube 134. Mercury is encapsulated in the glass tube 134. Each end portion of the glass tube 134 is fused to a substantially hemispherical form by heat and thus forms a dome portion. The outer conductor 135 penetrates the dome portion.

Each bolt 136 is a one-piece component, which may be formed by bending or forging a metal plate (e.g., stainless steel), which is formed into a predetermined shape through perforation. Bolt 136 includes a body 137 and a lead portion 140. Body 137 generally forms a concentric cylindrical shape with glass tube 134. Inner diameter of body 137 is adjusted to be slightly larger than diameter. outside of the glass tube 134.

Three pairs of elastic snap portions 138A, 138B are formed in body 137 by making slot-like cuts in their portions, which are arranged at uniform angular intervals along the circumferential direction.

A first elastic gripping part 138A, i.e. one of a pair of elastic gripping parts 138A, 138B, is generally formed as a laterally extending cantilever portion (specifically in an oblique direction). slightly sloping radially inward), which is capable of elastic and radial deflection with a point supported at its proximal end (or anterior end). A curved portion 139 is formed in the extreme distal portion (or rearmost portion) of the first elastic snap portion 138A so as to bend in an obliquely sloping radially outward direction. The outer curve surface (or inwardly facing surface) of the curved portion 139 is provided as a contact point when abutting the outer circumferential surface of the glass tube 134. The imaginary line connecting the contact points provided in the first three parts Gripping Points 138A form a concentric circle with body 137. The diameter of the imaginary circle, when the first gripping parts 138A are not forced to elastic deflection or are in a free state, is adjusted to be smaller than that the outside diameter of the glass tube 134.

A second elastic gripping part 138B, i.e. the other pair of elastic gripping parts 138A, 138B is disposed circumferentially adjacent to the first elastic gripping part 138A and is generally formed with a portion in cantilever extending anteriorly or inversely from the first elastic snap portion 138A (specifically, in an oblique direction, sloping slightly, radially inward), which is capable of elastic and radial deflection with a supported point at its proximal end (or posterior end). The distal end of the second elastic gripping part 138B is provided as a contact point when resting on the outer circumferential surface of the glass tube 134. The imaginary line connecting the contact points provided in the three second parts clamping bands 138B form a concentric circle with body 137. The diameter of the imaginary circle, when the second clamping elastic parts 138B are not forced to elastic deflection or are in a free state, is adjusted to be smaller than outer diameter of the glass tube 134.

In body 137e, a pair of protective portions are formed as cantilevered portions that protrude anteriorly from their anterior extreme edge. The pair of protective parts is circumferentially spaced and extends linearly from the body 137 so that it is level with the same BO. The conductive portion 140 is provided as a cantilever portion extending anteriorly between the pair of protective portions. The conductive part 140 includes a continuous long portion 141 continuous with the anterior end of the body 137 and a cylindrical portion 142 which still protrudes anteriorly from the anterior (or distal end) of the long extending portion 141a of the body. 137 to be flush with body 137 and parallel to its geometrical axis and further includes an intermediate portion 141b extending radially inwardly from the distal end of proximal portion 141a toward the geometric axis of body 137. The cylindrical portion 142 is connected to the distal end of the distal portion 141c. The width of the long portion 141 is set to be sufficiently small for the length of the long portion 141. Therefore, the long portion 141 is capable of elastic deformation in the radial direction of body 137, elastic deformation in a direction intersecting with the radial direction (and intersecting with the radial direction (and intersecting with the longitudinal direction of the long portion 141) and the torsional elastic deformation around the long portion 141 itself as the geometry axis.

The cylindrical portion 142, which may be formed by curvature of a laterally extending portion of the distal end of the long portion 141 in a cylindrical shape, is arranged substantially and coaxially with the body 137. The cylindrical portion 142 is capable of displacement around the geometric axis of bolt 136 and radial displacement due to the elastic deflection of the long portion 141.

Glass Bolt 136 to Glass Tuho 134

In the following, an assembly process for fixing a bolt 136 to a glass tube 134 will be explained.

During the assembly process, while a bolt 136 and a glass tube 134 are held by respective holding devices (not shown), bolt 136 and glass tube 134 are moved relative and coaxially to approach each other. Thereby, the body 137 is engaged in the glass tube 134. When the body 137 begins to engage, the contact points provided at the distal extreme positions of the three pairs of elastic gripping parts 138A and 138B have elastic contact with the outer circumference of the body. glass tube 134. The contact points slide on the outer circumferential surface of glass tube 134 as the assembly process proceeds. Then, the tip of the outer conductors 135 having passed through the body 137 begins to enter the hollow part of the cylindrical portion 142. When holding devices have then reached predetermined end positions, the bolt 136 and the glass tube 134 are positioned axially at the appropriate positions, resulting in the outermost tip portion of the outer conductor 135 circumferentially surrounded by the cylindrical portion 142. At this time, the outermost tip portion of the outermost conductor 135 will not protrude greatly from the front end of the cylindrical portion. 142. That is, it projects slightly out of the cylindrical portion 142 or is aligned with the front end of the cylindrical portion 142 or alternatively is located within the cylindrical portion 142.

Thereafter, the cylindrical portion 142 is secured to deform with diameter reduction. After being secured, the cylindrical portion 142 is electrically and conductively fixed to the outer conductor 135 by welding and, consequently, the bolt 136 is integrated with the glass tube 134.

Then the assembly process is completed and the discharge pipe 115 is completed.

When the bolt 136 is secured to the glass tube 134, the body 137 is held concentrically in the glass tube 134 due to the elastic holding function of the three pairs of elastic gripping parts 138. A gap (air gap) is trapped between the the outer circumference of the glass tube 134 and the inner circumference of the body 137 so as to extend substantially substantially the entire circumference.

Instead of the cylindrical portion 142, a U-shaped connecting portion 142a may be provided as shown in Figures 36 and 37. In that case, after a glass tube 134 is fitted into a bolt 136, the shaped connecting portion of U 142a is bent so as to surround the outer conductor 135 to obtain electrical connection between the outer conductor 135 and the connecting portion 142a. According to the embodiment, thus including the U-shaped bendable connection portion 142a, the electrical connectivity to the external conductor 135 may be further improved. Mounting Discharge Tube 115 on Relay Connectors

The outlet assembly 115 thus assembled is secured to the relay connectors 114. At the time of attachment, the discharge pipe 115, held in a horizontal position, is moved to the front face of the chassis 113 and the end portions and bolts 136 of glass tube 134 are fitted into container spaces 123 of relay connectors 114 on the front side. At present, the pair of elastic compression portions 132 are pushed by bolt body 136 to open vertically due to elastic deflection. After the body 137 has passed through the shorter distance portions of the compression elastic pair pair 132, the body 137 is pulled deep and into the container space 123 due to the elastic recovery forces of the elastic compression portions 132, resulting in in the body 137 resting on the bottom of the container space 123. Then the discharge tube assembly 115 is complete.

The discharge tube 115 thus assembled is held by the pairs of elastic compression portions 132 in their end portions and, accordingly, is secured to the chassis 113 by relay terminals 131 and the brackets 120 provided as the mounting bases of the relay terminal 131. At this time, the weight of the discharge pipe 115 is received only by chassis 113 via the relay connectors 114. That is, the external conductors 135 will not be under load due to the weight of the discharge pipe 115.

The pair of elastic compression parts 132 may have elastic contact with the circumference surface! 137, and thus the outer conductor 135 is electrically and conductively connected to relay terminal 131 via bolt 136. Further, the glass tube 134 is maintained due to the elastic restoration forces of the pair of elastic parts. 132 so as to be compressed against the concave portion 127 of the plug 126. Therefore, when viewed along the axial direction of the discharge pipe 115, the body 137 appears to be positioned to overlap also with the plug 126. That is, the extreme edge of the body 137 on the opposite side of the conductive part 140 is partially positioned in proximity to the plug 126 so as to be partially flush with it.

The extended portion 129 is formed on the outer surface of the bracket 120, which is perpendicular to the surface of the chassis 113 and includes the exhaust opening 125 of the container space 123 so as to protrude between the chassis 113 and the opening. 125 and extend along the surface of the chassis 113. This results in a long drag distance from the interior of the container space 123 to the front surface of the chassis 113. Thus, a leakage from the discharge pipe 115 maintained in container space 123 until chassis 73 off bracket 120 can be prevented.

Power Panel Overview

Each power panel 116 includes a circuit board 117 having a circuit formed on its rear surface (i.e. the surface on the opposite side of chassis 113), electronic components 119 mounted on the rear surface of circuit board 117, and a plurality. of on-board connectors 118 mounted on the rear surface of the circuit board 117. The circuit board 117 has a vertically elongated rectangular shape as a whole and is formed using a copper-coated laminated panel and phenolic paper base (known as a phenolic role). The plurality of socket holes 117H having a vertically elongated rectangular shape are formed through the circuit board 117 to extend from the front to the rear side. The plurality of plug holes 117H are arranged vertically along the side edge of the circuit board 117 to correspond to the relay terminals described above 131 (or relay connectors 114). Each on-board connector 118 includes a housing made of synthetic resin and an output terminal (not shown) that is completely contained in the housing and is made of metal (eg nickel silver). The on-board connectors 118 are arranged along the Yard edge of the circuit board 117 to correspond with the respective plug holes 117H. A locking space (not shown) is formed on the outer surface of the housing to correspond to the respective locking holes 117H and the output terminal is partially exposed to the locking space.

Although circuit board 117 is kept parallel to chassis .113, power panel 116 is moved to and attached to chassis 113 on the rear side. At the time of attachment, the wall portions 122 of the relay connectors 114 and the panel connection portions 133, disposed along the wall portions 122, penetrate the circuit board 117 through the plug holes 117H and are inserted. into on-board recesses 127 of on-board connectors 118 o, so .118 on-board connectors are plugged into relay connectors 114 and output terminals are conductively connected to relay terminals 131. Operational Effects of the Mode 2

In the present embodiment 2, when a discharge pipe 115 is supported on relay connectors 114, the plugs 126 lock the bolts .136.

Therefore, the discharge pipe 115 is prevented from axial movement relative to the relay connectors 114. That is, if a force is applied to the discharge pipe 115 in order to cause a right movement, the plug 126 reaches the left adjacent bolt 136 is secured to the left end portion of the discharge pipe 115 so that the movement of the discharge pipe 115 to the right is restricted. If a force is applied to the discharge pipe 115 to cause leftward movement, the plug 126 reaches the right adjacent bolt 136 attached to the extreme right portion of the discharge pipe 115 so that the Movement of the discharge pipe 115 to the left is restricted. In this way, the axial movement of the discharge pipe 115 to the right or left is restricted and therefore the outer conductor tip 135 is secured so as not to hit the wall 122 of the container space 123 on the opposite side of the opening. exhaust system.

The plug 126 may engage the end edge of the bolt 136 and lock it, and therefore a hole that can engage the plug 126 need not be formed in the outer circumference of the bolt 136. Thus, the processing cost can be reduced. and reduction in bolt resistance 136 may be prevented.

In the case of a construction in which a plug 126 may engage with the extreme edge of a bolt 136 on the side of the conductive part 140, the conductive part 140 extending from the extreme edge of a bolt 136 may prevent the end edge of the bolt 136. bolt 136 engages with plug 126, when bolt 136 is engaged at some angle about its geometrical axis. However, in the present embodiment 2, the plug 126 is arranged to engage with the end edge on the opposite side of the conductive part 140. Therefore, the conductive part 140 will not prevent the bolt 136 from engaging with the plug 126 and, consequently, the bolt 136 may unfailingly engage with the plug 126.

The conductive part 140 includes a cylindrical portion 142, which may be circumferentially connected to the outer conductor 135 so as to surround it. In this manner, the conductive part 140 may be prevented from disengaging from the outer conductor 135. That is, the cylindrical portion 142 will not disengage from the outer conductor 135 when the cylindrical portion 142 is secured. Therefore, the conductive part 140 can be unfailingly connected to the external conductor 135.

The fitting margin of a bolt 136 with a plug 126 corresponds to half the dimensional difference between the outer diameters of the glass tube 134 and the bolt 136. In the present embodiment 2, the bolts 136 are concentrically held in a glass tube. 134 due to the elastic gripping parts 138A and 138B. Therefore, if the bolt 136 is set to be large, a large dimensional difference can be trapped between its inner diameter and the outer diameter of the glass tube 134. Thus, the margin for engaging the bolt 136 with the plug 126 can be resulting in a safe restriction of movement of the discharge pipe 115. The concave portion 127 is formed in a plug 126 so as to abut the outer circumference of a glass tube 134 when the bolt 136 engages with the plug 126. Still , the pair of elastic compression parts 132 capable of compressing the discharge tube 115 towards the concave portion 127 is provided in the relay connector 114. Specifically, the pair of elastic compression parts 132 compresses the discharge tube 115 in towards the concave portion 127, obliquely from above and obliquely from below, that is vertically and symmetrically. In this way, the glass tube 134 is prevented from disengaging from the concave portion 127, and thus the engagement of the bolt 136 with the plug 126 can be safely maintained.

Relay connector 114 is formed by mounting a relay terminal 131 on a bracket 120 made of synthetic resin. In the present embodiment 2, the plug 126 is formed in the synthetic resin support 120. Therefore, a plug need not be formed in the relay terminal 131 and thus the material for manufacturing the relay terminals 131 can be formed. be reduced. Considering that the material cost for synthetic resin is generally lower than for metal, the material cost for relay connectors 114 may be reduced according to the present embodiment 2. Mode 3

In the following, an embodiment 3 of the present invention will be explained with reference to figures 20 to 35. In the present embodiment 3, the constructions of means for supporting a discharge pipe 115 differ from those of embodiment 2 above. The other constructs are similar to embodiment 2 above. Therefore, the same constructs are designated by the same symbols and explanations for their constructions, operations and effects are omitted.

Grounding Element Overview 150

In embodiment 2 above, the end portions of a discharge pipe 115 are supported by relay connectors 114, each of which includes a support 120 and a relay terminal 131. In the present embodiment 3, one of the end portions of a discharge pipe 115 is supported by the same relay connector 114 as embodiment 2, while the other extreme portion of the discharge pipe 115 is supported by a grounding element 150.

The grounding element 150 includes an extended support plate 151 fixed to the chassis 113 to be along one of its side edge portions and further includes a plurality of grounding terminals 152 conductively mounted to the front surface of the frame. mounting plate 151. Mounting holes 151H are formed through the mounting plate 151 to match three to one with the grounding terminals 152. The mounting plate 151 is formed of a substrate or a mounting plate. Metallic

On the other hand, each grounding terminal 152, which may be formed by bending a metal plate (e.g., nickel silver) that is formed into a predetermined shape through perforation, includes a base portion 153 and a pair of elastic compression portions .154 extending vertically and symmetrically from respective upper and lower edge portions of base portion 153 to the front side. Further included is a plug 155 extending from one of the lateral edge portions of the base portion 153 to the front side.

The pair of elastic compression portions 154 are provided at the side edge portion on the opposite side of the plug 155 to form bulging curves towards each other. The elastic compression parts 154 are capable of elastic deflection to increase the distance between them. The minimum distance between the pair of elastic compression parts 154, when the elastic compression parts 154 are free of elastic deflection, is set to be smaller than the outer diameter of the glass tube 134 of a discharge tube 115.

The plug 155 is raised from the base portion 153 to form a right angle with the geometric axis of the discharge pipe 115. A concave portion 156 is formed on the plug 155 to surround it in a substantially circular arc.

In a relay connector 114 of mode 2, a pair of guide portions 128 are raised from respective upper and lower sides of concave portion 127 of plug 126. However, in the presence of mode 3, the heights of raised portions of respective sides upper and lower portion of concave portion 156 of base portion 153 are reduced to short. That is, means corresponding to the guide portions 128 of embodiment 2 are not provided. Therefore, a metal material required for grounding terminals 152 may be reduced compared to the inclusion of guide portions.

Three leg portions 157 are further formed in the base portion 153 to be integrated with it. Two of the three leg portions 157 are provided between the elastic compression portions .154 and the plug 155 so as to project from respective upper and lower edge portions of the base portion 153 to the opposite side of the elastic compression portions. 154 or to plug 155 (ie to the rear side). The remainder of the leg portions 157 are provided at the side edge of the base portion 153 on the opposite side of the plug 155 so as to project from the intermediate position between the elastic compression parts 154 to the opposite side of the elastic compression parts 154 or to the plug 155 (ie to the rear side).

The grounding terminal 152 is not housed in an element such as a plastic housing, i.e. rarely provided and is conductively fixed to the support plate 151 by welding or the like so that its leg portions 157 penetrate through mounting holes 151H. Thus, the plurality of grounding terminals .152 are mounted on the common support plate 151 and thus are conductively connected to each other via the support plate 151. Power panels are not connected to the grounding elements 150 and the plate. Bracket 151 is conductively connected to the chassis. Mounting Discharge Tube 115 to Ground Terminal 152

When a discharge pipe 115 is attached to a grounding terminal 152, the discharge pipe 115, held in a horizontal position, is moved to the front face of chassis 113 and the end portion and bolt 136. of the glass tube 134 are fitted between the pair of upper and lower compression elastic parts 154 of the front side. At the moment, the pair of elastic compression parts 154 are pushed by the body 137 of the bolt 136 to open vertically due to the elastic deflection. After the body 137 has passed one through the shorter distance portions of the compression elastic pair pair 154, the body 137 is pushed to the base portion 153 due to the elastic restorative forces of the elastic compression portions. 154 resulting in the body 137 resting on a base portion 153. Then, the attachment of the discharge tube 115 is complete. The other extreme portion of the discharge pipe 115 is fixed to a relay connector 114 in a similar manner to embodiment 2 above.

The discharge pipe 115 thus assembled is supported by the relay connector 114 and the grounding element 150 in their respective end portions. The pairs of elastic compression portions 132, 154 may have elastic contact with the outer circumferential surfaces of the bolt bodies 137 and thus the outer conductors 135 are electrically and conductively connected to the relay terminal 131 and the grounding terminal 152 by means of bolts 136. Further, the entire glass tube 134 is retained due to the elastic restorative forces of the pairs of compressive elastic parts 154 so as to be compressed against the concave portions 127, 156 of the 126. 155. Therefore, when viewed along the axial direction of the discharge pipe 115, the body 137 appears to be positioned to partially overlap the plug 126 or 155. That is, the extreme edge of the The housing 137 on the opposite side of the conductive part 40 is positioned axially in proximity to the plug 126 or 155 so that it is partially facing.

As shown in FIGS. 38 and 39, protective portions 551 may be provided at ground terminal 152. Each protective portion 551 includes a restraining portion 552 for an elastic compression portion and further includes a support portion 553 to support the support plate. . When the grounding terminal 152 is mounted and secured to the support plate 151, the support portions 553 support or are located near the support plate 151. If a kind of external force is applied to the elastic compression portions 154 such that they are pushed open, they first come in contact with restraining portions 553 during the opening stroke. The bearing portions 553 serve as supports to prevent the protective portions 551 from folding when an additional load is applied. The protective portions 551 are connected to the feet of the elastic compression portions 154, and therefore the supporting portions 553 will be formed laterally to the connecting portion so that the supporting portions 553 function. Note that the support portions 553, located further away from the connection portion, are more effective.

Operational Effects of Modality 3

In the present embodiment 3, when a discharge pipe 115 is supported on a relay connector 114 and a grounding element 150, the plug 126 of the support 120 and the plug 155 of the grounding terminal 152 block the bolts 136 at their respective ends. discharge pipe 115. Therefore, the discharge pipe 115 is prevented from axial movement relative to the relay connector 114.

That is, if a force is applied to the discharge pipe 115 so as to cause movement from the relay connector side 114 to the grounding member 150, the bolt 136 is secured to the end portion of the discharge pipe 115 on the connector side. The relay 114 is caught by the plug 126 of the holder 120, so that the movement of the discharge pipe 115 to the grounding element 150 is restricted. If a force is applied to the discharge pipe 115 so as to cause movement of the grounding element side 150 to the relay connector side 114, the bolt 136 is secured to the end portion of the discharge pipe 115 on the side of the discharge element. Grounding 150 is caught by the plug 155 of the grounding terminal 152, so that the movement of the discharge pipe 115 to the side of the relay connector 114 is restricted.

In this way, the axial movement of the discharge pipe 115 to the right or left is restricted and therefore the tip of the outer conductor 135 is prevented from hitting the wall of the container space 123 on the opposite side of the exhaust port. 125 or hitting the chassis sidewall 113.

The concave portion 156 is formed in the plug 155 of a grounding terminal 150 so as to abut the outer circumference of a glass tube 134 when bolt 136 is engaged with the plug 155.

Further, the pair of elastic compression parts 154 capable of compressing the discharge tube 115 towards the concave portion side 156 is provided at the grounding terminal 152. Specifically, the pair of elastic compression parts 154 compresses the discharge tube. discharge .115 towards the side of the concave portion 156, obliquely from above and obliquely from below, that is vertically and symmetrically. In this manner, the glass tube 134 is prevented from disengaging from the concave portion 156, and thus the engagement of the bolt 136 with the plug 155 can be reliably maintained.

In the grounding element 150, the plugs 155 are integrated with the respective grounding terminals 152 provided as means for conductive connection to the bolts 136. Thus, the number of components can be reduced in the present embodiment 3 compared to the inclusion of the plugs provided as separate elements from grounding terminals. Other Modalities
